Hi everyone,
I’m developing an iOS application and I’m wondering whether it is possible to position the app on either the left or right side of the screen when running in a dual-window/multitasking configuration.
If the app does not occupy the entire screen, can I customize the remaining empty space by assigning a background color or displaying an image?
Additionally, if I place a visual element or background in the central/remaining area, could this cause any issues with touch interaction or hit-testing? In particular, I’d like to understand whether the system would still correctly route touch events to the active application, or whether the additional area could interfere with the app’s clickable elements.
I'd recommend you check out the video "Prepare your app for iPhone Duo":

When not built with the iOS 27.1 SDK, apps will not take up the entire screen space. But after building with that SDK, they will.
Prior to building with the iOS 27.1 SDK there's no support to modify the system provided background as shown in the video.
Additionally, there is no support to position your app's scene on either the left or right side of the screen when the device is open.
